PLEASE ANSWER I NEED HELP In a family, the father is affected by a genetic disorder. The son in the family has the same disease, but the daughters do not have it. What type of inheritance is this? A. Y-linked B. X-linked C. polygenic D. codominant

A. Y-linked.

Explanation:

Males have one Y chromosome and one X chromosome, while females have two X chromosomes.

If the father is affected by a genetic disorder, that means it will be passed down to only sons in the family, not females, since females do not have a Y chromosome.

This would mean the genetic disorder is Y-linked, and only on the Y chromosome, which is specific to males.

A. Y-linked

Explanation:

Males have one Y chromosome and one X chromosome.

Females have two X chromosomes.

Father is affected by a genetic disorder. The son has the same disease. The daughters are not affected because they do not have Y chromosomes.

The father and son have Y chromosomes, so the type of inheritance is Y-linked.

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.
